Onan Micro Quiet 4000 Gas Powered Generator Won't Crank

I had an Onan 4k on my motorhome. It had trouble starting, I eventually replaced the starter and that fixed it. I bought the starter on Amazon. My starter had gotten weak over time and I just didn't notice. The new starter spun the genset over much faster making it start easier. At times the old starter wouldn't spin the engine over and I would have to try several times.

I also had another issue with it where it would only start while holding the start button down. I replaced the control board and it fixed that.
